First Full Flash Site: Needs Critique and Solutions to Problems!

Hi! I just recently purchased Adobe Flash CS3 and have been playing around with it quite a bit. I have managed to make a couple small, simple flash projects, but I just finished my first “full flash site”. I would love it if you could take a look and tell me what you think.

The link is:

There is only sample content on it right now.
NOTE: I made this very basic so I could clearly learn the main aspects of a full flash site.

I do have 3 questions:
a) Where is the best tutorial to make a custom scroll bar for the boxes?
b) What is the best way to display content? Right now, it goes to basic text files.
c) How, if its at all possible, do I make the content include HTML or pictures or anything like that?

Thanks in advance!
